History

The service was launched on July 6, 2011. The Intersango open source software that the exchange runs on was announced on March 17, 2011. In September, 2011 the exchange began using a new version of the Intersango open source exchange project with two currency markets (BTC/EUR, BTC/USD) live under the Intersango brand and plans made for the third (BTC/GBP) when Britcoin accounts are migrated at a future date.

On October 9, 2012, the exchange announced imminent plans to shutter its BTC/USD market.
